backsplass 

When taking a massive dump, backsplass is the the effect of the dump causing water to splash against your ass.

Not only did I have to whipe my my anus, but I got water all over the rest of my ass. Fucking backsplass!

Backsplash Barrier 

The layer of toilet paper you put in the toilet before you take a dump. Helps to prevent backsplash and also makes crapping quieter as there are no more splashing noises.

A: Why'd you take so long, bro?
B: Dude, I had to take a shower after I took a dump due to all the backsplash on my ass.
A: Gross. Next time don't forget the backsplash barrier.

Girl1: I hate pooping! It's embarrassing coz people can hear you sometimes.
Girl2: Hellooo, backsplash barrier? Keeps your butt clean and also makes pooping virtually soundless.

Backsplash protection 

When one is on their way to excrete the devil from their bowels, you place a thin sheet of toilet paper on the surface of the water in the toilet bowl giving you backsplash protection

"I just dropped the motherlode in that toilet."

"I bet your ass got drowned in backsplash."

"Nah i used backsplash protection."

Bubbler BackSplash 

The splashing of dirty bong water on your lips while you are smoking marijuanna out of a water pipe.
